Application filed November 10, 1915. Serial No. 60,742.

To all whom t may concern:

\Be it known that I, JAMns H. Bovn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Taming-Shuttles, of which thefollowing is a specification.

rEhe present invention constitutes an improvement upon the tattingshuttle described in my pending application No. 57127, tiled oet. er,1915.

The primary object is to provide an improved device of such constructionas to facilitate the removal or withdrawal o' the bobbin, either forrfa-winding purposes, or for the purpose of substituting another bobbincontaining a di'lierent thread.

A further object is to so construct the improved device as to providethe shuttle proper with a thread-hook.

The invention is illustrated in its preerred embodiment in theaccompanying drawing, in which-Figure 1 is a side view of a tattingshuttle constructed in accordance with this invention; Fig. 2, a planview of the device; Fig. 8, a view similar to Fig. 1, but showing thebobbin withdrawn from the housing aiiorded by the sides of the shut tle;Fig. a, a plan view with the bobbin in the position shown in Fig. 3;Fig. 5, a side view with the shuttle reversed from the position shown inFig. 1; Fig. 6, an enlarged broken sectional View, illustrating theinanner inwhich the sides, or bows, oi' the shuttle are united at theirend portions, this view showing also the pivotal connection ot theswinging arm which carries the pivot for the bobbing Fig. 7, an enlargedbroken sectional view taken as indicatedv at line 7 of Fig. 1; Fig. 8,an enlarged broken view of the arm which carries the bobbin or spool,this view illustrating the furcated expansilole pivot, or trunnion, uponwhich the spool is demountably carried; and Fig. 9, a broken sectionalview of a slight modification.

In the construction illustrated, Arepre sents the shuttle proper, or theframe of the device; B, an arm pivotally mounted in said frame; and C, aremovable spool or bobbin carried by the arm B, the arm and spool beingnormally housed between the bows of the shuttle.

The 'frame A preferably comprises e pair of resilient, pointed sidemembers or bows, 1 and 2, whose extremites are permanently joinedtogether. In the illustration given the bows are of metal and areprovided at their extremities lwith inwardly-struck embossments 3. Oneof the bows is provided at the cmbossments 3 with periorations Ll; andthe other bow is provided at the embossments' with inwardly-struck lugsl, which pass through the perforations Ll and are clenched. The lugs Laafter clenching, are disposed within the depressions aiorded by strikingthe metal inwardly to form the embossments 3. After the bows are unitedin the manner indicated in Fig. 6, the tips are touched with solder, asindicated at 5, to give the extremities of the shuttle the character ofan integral formation.

It is preferred to notch the edges of the pointed extremities of thebows at one end of the shuttle to provide a small threadhook G, which isundercut so as to provide a distinct barb, which may be used to engagethe thread and pull it through the loop.

The arm B may be formed of resilient sheet metal, such as brass. The armisl prelierably of the angular form shown, having the extremity orv itslong arm connected, by a pivot 7, to one bow of the frame A, near oneend of the device. The short arm or angular' projection of the member Bcarries a laterally projecting pivot or trunnion 8, upon which thebobbin or spool C is demountably carried. The trunnion 8 may be Jformedby providing the short member 8a of the swinging arm or link B with lugsor projections 8", which are bent at right angles, so as to extendlaterally from the member 8, as indicated in Fig. 8. The turcations 8are made concavo-convex, and the extremities are bent apart, asindicated at 8c. At the elbow of the link B is provided a smallthumb-piece 8d, which may be used to swing the link from its normallyhoused position. In the housed position, the thumb-piece 8l engages oneedge of one of the bows of the shuttle, thus acting as a stop. 'In thisposiltion, the spool C is properly centered and engages aninwardly-struck central embossment 9, with which the side member 2 ofthe shuttle is provided.

The spool C comprises a short barrel l0 and flanges 11. The spool may beslipped onto the trunnion 8, the furcations 8 torming the trunnion,yielding somewhat as the spool is forced onto the trunnion, and theprojections 8 afterward serving to prevent side members l and 2, owingto their resilient character, will spring apart as the spool is forcedto the centered position, thus the projection 9 serves as a catch orretainer to hold the spool properly centered, but without interferingwith the revolution of the spool.. Inasmuch as the side members or .bowsof the shuttle are held separated slightly more than when the spool iswithdrawn from the housing, it will be evident that the spool isfrictionally held, so that it will not rotate too freely in the tattingoperation, and will hold the thread from unwrapping in case the shuttleis dropped.

The tatting operation is carried on in the usual manner.' When desired,the link or swinging mounting l5 may be withdrawn from the housing, anda fresh supply of thread may be wound upon the bobbin C; or, it desired,the spool or bobbin may be removed and replaced by another spoolcontaining a different kind of thread. rThe thread, in the illustration,is designated l2; lt will be noted from. Fig. 1l that the spool C isfree at one side when the mounting B is in the unsheathed position. Thisenables thread to be wound readily upon the spool.

The construction of the device is such that the spool or bobhin will beautomatically centered in the operation of sheathing it.`

. ln other words, it is only necessary to swing the link B inwardlyuntil the thumbpiece 8d engages the shuttle frame, and the spool will beautomatically centered and properly retained in the 5'traine ,until Aitis forcibly withdrawn. In the mod'itlcaticn shown in Fig. 9, theconstruction is similar to that described, except that the link B (whichcorresponds with the link B) is provided-with an embossment 9a whichco-acts with aspoolcentering perforation l with which the bow i l isprovided. ln this modification, the embossment 9 or the bow 2 isdispensed with.

The foregoing detailed description is given for clearness ofunderstanding only, and no unnecessary limitation should he understoodtherefrom, but the appended claims should be construed as broadly aspermissible in view of the prior art.

What l regard as new and desire to secure by Letters Patent is:

l. A tatting shuttle comprising a pair of bows, a link pivotallyconnected therewith and provided `with a laterally projecting trunnionat its free end, and a spool demountably carried by said trunnion.

A tatting shuttle comprising a pair of bows, a link pivotally connectedtherewith and provided with a laterally projecting, eX- pandingtrunnion, and a spool demountably carried by said trunnion.

A tatting shuttle comprising a pair of4 resilient bows having their endportions connected, a link pivotally connected therewith and adapted tobe sheathed between the bows, said link provided at its free end with alaterally projecting trunnion adapted to be held between said bows bythe resilience ofthe bows, and a spool mounted on said trunnion.

Ll. A tatting shuttle comprising a pair of resilient bows, one oi' whichis provided with a spool-centering device, a link pivotally connectedwith one of the bows and provided with a laterally projecting trunnion,and a spool carried by said trunnion.

5. A tatting shuttle comprising a pair of resilient bows, havingconnected extremities, one of the said bows being provided with aspool-centering device, avlink pivotally connected with one of saidbows, and equipped with a. laterally projecting trunnion, and with athumb-piece, and a spool, mounted on said trunnion.- i`

G. A tatting shuttle-comprising a pair of resilient bows,having'conneted extremities,

one of said'bows having a spo ol centering device,Vv van angularlink.-pivotallyleonnecte with onel of the bows-and 'adapted to be housedbetween vthe bows, said link provided with a laterally projectingtrunnion, and a spool mounted on said trunnion.
